Onshore pipelines have traditionally been designed with a deterministic stress-based methodology. The changing operating environment has, however, imposed many challenges to the pipeline industry, including heightened public awareness of risk, more challenging natural hazards, and increased economic competitiveness. To meet the societal expectation of pipeline safety and enhance the competitiveness of the pipeline industry, significant efforts have been spent for the development of reliability-based design and assessment (RBDA) methodology. This paper will briefly review the technology development in the RBDA area and the focus will be on the progresses in the past years in standard development within the American Society of Mechanical Engineers (ASME) and the Canadian Standard Association (CSA) organizations.
